PLOW.

Application filed May 21, 1923.

This invention relates to improvements in plows.

One of the objects of this invention 1s to improve the structure otplows, to strengthen the same and enable them to be readily assembledand disassembled.

` Another obj ect of the invention is to provide means between theground working pieces and the seat bar of the plow to regulate at willthe depth at which the share is to operate in the ground.

Another obj-ect of the invention is to provide an improved constructionof the share and its supporting means to render them more durable.

The invention is described with reference to the iigures ot the annexeddrawing, in which:

Fig. 1 is a side elevation of a moulding r plow provided with theimprovements forme ing the subject matter of this invention.

Fig. 2 is a plan of the same.

Fig. 3 is a longitudinal vertical section on line 3-3 of Fig. 2.

Fig. 4 is a perspective detail view of the mould-board.

Fig. 5 is a perspective detail ot the share and its support.

Fig. 6 is a side elevation of a modified form of plow, arranged for useas a trench plow.

Fig. 7 is a plan of said modified form.

Fig. 8 is a partial longitudinal vertical section on line 8 8 of 7.

Fig. 9 is a horizontal section on line 9--9 of Fig. 6.

Figs. 10, 11 and 12 are 'pers}i ecti\'fe views, respectively, oi theshare and its support,

f of the mould-board and ot the connecting nece.

l In the drawing, 1 indicates the beam of the plow which is secured bybolts 2 and nuts 2 in the fork at the front end of the seat bar 3 of theplow. Said bar is metallic and ot curved form, having a widened centralportion 4 provid-ed with a longitudinal slot 4 for the objecthereinafter explained. The seat bar 3 is pivotally connected by ahorizontal pin 5 secured in a slot 7 formed in the heel 8 of the plow bya pin 5 and split pin 6. Said heel is curved rearwardly atits upper endand terminates in lateral wings 9 which are also rearwardly and upwardlyinclined, and to which are secured the handle bars 11 of the plow bybolts 10.

Serial No. 640,480.

Hand grips 11 are secured to the bars 11, and the latter are connectedtogether by a cross bar 12. Shank of heel 8 is inserted in a slot of bed13 which is made of forged iron and is integrally connected at'its Jforeend to the share which is made of the same class of material forming thebed 13. Said share is made of flat iron comprising an upper portion 14,al iront upwardly directed abutment 14'* and a side portion downwardlyinclined 14 which forms an arcuate angle with the wedge shaped end ofthe bed 13. The part 14 is designed to receive the lower fore portion otthe mould-board 15 which projects laterally and is integral with acurved upwardly directed bar 16. Mouldboard 15 is fixed to the part 14by bolts 17 which pass through corresponding holes 18 land 19 inmould-board 15 and part 14 respectively and are secured by nuts 20. Thebar 16 has at a distance above the mouldboard 15 a lateral abutment 21which bears on the upper end of a curved link 22 connecting the bar 16with the bed 13 and which is secured by pins 23 and 24 and nuts 25and26. The mould-board is also connected to bed 13 by a brace 27 havingter minal eyes 27', one or' which is iixed to the mould-board 15 by ascrew 28 passing through a hole 29 in the mould-board and secured by acorresponding nut. The inner eye 27 of brace 27 is connected to aprojection 30 of the seat bar 13 by means oi a pin 31 and nuts 32.

From the upper end loil bar 16 projects a threaded stem 33 which passesloosely through slot 4 of seat bar 4 and is iixed with respect to thesame by means of an upper wing nut 34, a washer 35 and a lower wing nut36.

At the iront end of the beam 1 is arranged a clevis 37 provided with aneye 33 and connected to the sides of the beam b means ot bolts 39. Asmall plate 40 is iXed von th-e upper tace `of beam 1 by bolts 41 andhas a link 42 connected to an eye 41 of said plate 40. A vertical bar 44is secured to the beam by a clamp 43 and carries the guidingwheel 45.

To regulate the depth at which the point 14" of the share is operated inthe ground, nuts 34 and 36 are loosened, the threaded stem 33 isadjusted in the slot 4 of seat bar 3 to the desired position, and thesaid nuts are then tightened. As the seat bar 3 is ISL:

,minate at its lower end the heel 8 and the vertical knife 48, thelatter replacing the bar 16 of the form previously described. Said knife48 has the threaded stem 33. 1n this form, the share is not providedwith the part 14 and the 1nouldboard 15 is independent and has aninverted surface at the rear part with respect to the front part forinverting the ground raised by the share. Share 15 is secured to themould-board 14l by means of a union plate 48 which has two rows of holes49 andV 50 and is applied under the adjacent portions of the mouldboard15 and of. the share 14, and is fixed by rivets 50 which pass throughcorresponding holes 51 and 52 respectively formed in the mould-board' 15and the .share 14". The mould-board; 15 is reinforced by braces 53 and54 similar to brace 27 previously described and by means of which themould,- board is connected to the bed 13'by means of countersink screws55 and 56' which pass through side holes 57 and. 58 in the supportingclamps 46 and 47 and through holes formed in the Shanks of the heel' 8and of the knife 48 and which are secur-edvby the nuts 59 and 60respectively.

This modified form of plow is adjustable according to the depth it isdesired to plow the ground, in theV same manner as previously explainedfor the moulding plow.

It should be understood that the details of construction of the parts ofthis plow can be slightly varied without altering the essentialcharacter of the invention, which is as pointed out in the appendedclaims.

What I claim is:

1. A plow comprising a beam having a downwardly-curved standard portion,a bed member, a share integrally formed thereon, a connection memberadjustably connected to the beam and rigidly connected to the bedmember, handles, and an element to which said' handles are rigidlyattached, said element being pivotally connected to said downwardlycurved standard portion and rigidly connected to said bed member.

2. A plow comprising a beam having a downwardly-curved standard portion,a bed member having a socket at the middle portion and' another socketat the rear portion, a share integrally formed on the fore portion ofthe hed member, a connection mem.- ber adj'ustably connected to the beamand rigidly connected to the bed member in the middle socket thereof,handles and an elem-ent to which said handles are rigidly attached,said' element being pivotally connected to saidl downwardly curvedstandard portion and rigidly connected to the bed member in the rearsocket thereof.y

In witness. whereof I' afiix my signature.

MANUEL BOUZO.
